500V Vishay Siliconix Power MOSFETs Feature 0.270 On-Resistance
Vishay has released three new 500-V MOSFETs that extend its Gen 6.2 n-channel planar FET technology to the TO-220, TO-220F, and TO-247 packages. The new SiHP18N50C (TO-220), SiHF18N50C (TO-220 FULLPAK), and SiHG20N50C combine their 500-V rating with low 0.270 Ω maximum on-resistance at a 10-V gate drive. This low RDS(on) translates into lower conduction losses that save energy in power factor correction (PFC) and pulsewidth modulation (PWM) applications in a wide range of electronic systems, including LCD TVs, PCs, servers, telecom systems, and welding machines.
In aFor reliable operation, the devices are 100 % avalanche tested and feature high single-pulse (EAS) and repetitive (EAR) avalanche energy capabilities. Peak current handling is 72 A pulsed and 18 A continuous. All three devices feature an effective output capacitance specification. Compared to previous-generation 500-V power MOSFETs, the new devices also feature improved transconductance and reverse recovery characteristics.
